The MiHigh infrared sauna blanket is the cheapest way to get a legitimate far-infrared sweat session at home — when it's on sale, which is most of the time. We've tested and tracked the sauna blanket category across our full blanket rankings, and MiHigh holds a specific position in it: the entry point. This review covers what the ~$179–$399 price actually buys, where the brand cuts the corners that HigherDOSE and Sun Home don't, and who should spend more.

MiHigh Sauna Blanket: Key Specs

One pricing note before anything else: MiHigh runs near-permanent promotions. The $399 list price is best treated as a ceiling — at the time of writing the brand's own US store showed $179, and sale prices between $179 and $349 have been the norm rather than the exception. Never pay list price for this blanket.

What the MiHigh Gets Right

Real heat at the lowest established-brand price

The core function works. Nine settings spanning 95–167°F give you genuine session control, and the 167°F ceiling matches the Sun Home blanket — only the HigherDOSE V4 goes higher, at 175°F. Users report a dripping sweat within about 15 minutes at setting 6, which tracks with how far-infrared blankets behave: because the heat is applied directly to your body rather than the air, the felt intensity runs well ahead of what the same number would feel like in a cabin sauna. The physiological response that makes blankets worth owning — elevated heart rate, heavy sweat, the post-session calm — is fully present here. Research on regular heat exposure suggests meaningful cardiovascular and recovery benefits, and the MiHigh produces the same core stimulus as blankets costing twice as much. (For the underlying evidence, see our breakdown of infrared sauna benefits.)

Sensible sizing and a simple controller

At 70.8 inches (180 cm), the MiHigh accommodates users up to roughly 6'4", with a 330 lb weight capacity — among the more generous dimensions in the category. The handheld controller is basic in a good way: temperature up/down across the nine levels and a timer that runs 30–60 minutes in 5-minute steps. There's no app, no Bluetooth pairing, nothing to update or troubleshoot. For a device you use lying down with your arms inside a hot cocoon, fewer features is the correct design decision.

The 30-day trial is genuinely risk-free — if you act inside it

MiHigh's 30-day money-back trial covers a full refund, and US shipping runs 3–8 business days. Thirty days is enough to learn whether you'll actually use a sauna blanket three or four times a week — most people know within two weeks whether the habit is sticking. It's a much shorter evaluation window than HigherDOSE's 120 days, but it's real, and for a habit-test purchase that's what matters. The practical advice from owners who've used it: keep your order confirmation and initiate any return early, because the brand's customer service response times are the weak link (more on that below).

It travels

The blanket folds into the included carry bag and weighs little enough to move between rooms, take to a second home, or pack in a car. A full infrared cabin can't follow you anywhere. This is a small thing until it's the reason you keep the habit through a house move or a season away.

Where It Falls Short

The post-sale experience is the documented weakness

This is the trade-off that defines the MiHigh, and it's not speculation — it's the consistent pattern in owner reviews over the past 18 months. Trustpilot complaints repeatedly cite slow customer service responses, difficulty processing returns, and — most importantly — reports of heating-element failures after 6–12 months of regular use. The blanket generally works as advertised out of the box; the question is what happens at month eight if it stops working, and the answer from a meaningful number of customers has been frustrating. A 1-year warranty technically covers that window, but a warranty is only as good as the support team honoring it.

The low-EMF claim is self-reported

Nearly every sauna blanket on the market claims "low EMF," and MiHigh is no exception — but the brand publishes no third-party lab testing to back it. HigherDOSE remains the only consumer blanket brand that posts independent EMF and VOC test results. To be clear, there's no published evidence the MiHigh's EMF output is problematic; the issue is that you're taking the manufacturer's word for it. If EMF documentation matters to you, that alone settles the brand choice.

Slower to heat than the premium options

Plan on 15–20 minutes of pre-heat before getting in — most owners switch the blanket on, then get changed and hydrate while it warms. The HigherDOSE V4 reaches temperature in 10–15 minutes. It's a minor friction, but if your sessions run 30 minutes, a 20-minute pre-heat means the total time commitment is nearly an hour.

The usual blanket constraints apply

The 60-minute timer is a hard ceiling, your head stays outside the blanket (so no ambient face/head heat as in a cabin sauna), and there's a single heat zone — the whole blanket runs at one temperature. None of these are MiHigh-specific failings; they're category constraints shared by blankets at every price. But if any of them is a dealbreaker, the answer is a cabin sauna, not a more expensive blanket.

MiHigh vs the Alternatives

The honest framing: inside the blanket, a MiHigh session and a HigherDOSE session feel more alike than the price gap suggests. What the extra ~$300–$500 buys is documentation (published safety testing), durability (better build quality and the longer track record), and a four-times-longer return window. Whether those are worth it depends entirely on how certain you are that this becomes a long-term habit. Our full sauna blanket rankings cover the complete field.

Who Should Buy the MiHigh

Buy the MiHigh if:

• You want the cheapest credible test of the sauna blanket habit — and it's on sale at ~$349 or less
• You'd rather risk $179–$349 on a 1-year horizon than commit $699 up front
• You're an occasional user (1–3 sessions a week) rather than a daily heavy user
• You fit within 6'4" and 330 lbs

Spend more if:

• You already know you'll use it daily — the heating-element failure reports cluster around heavy use, and the HigherDOSE's build quality and 120-day window are worth the premium
• Published third-party EMF/VOC testing is a requirement, not a preference — only HigherDOSE offers it
• Post-sale support matters to you — MiHigh's customer service record is the brand's weakest point

Skip blankets entirely if you want ambient heat, head exposure, or sessions longer than an hour — that's cabin sauna territory, and our sauna guides cover those options.

Our Verdict

The MiHigh infrared sauna blanket is a rational purchase at a deep discount and a questionable one at list price. At ~$179–$349 it's the cheapest way to find out whether the sauna blanket habit sticks — the heat is real, the 95–167°F range is properly usable, and the 30-day trial gives you an exit. At $399–$499, the Sun Home blanket is flatly the better buy, and at that point the case for stretching to the HigherDOSE V4 starts writing itself. We'd buy the MiHigh today only as a habit test, on sale, with eyes open about the customer service record — and if the habit stuck, we'd expect to upgrade rather than replace it like-for-like when it wears out. That's not a knock; it's exactly what an entry-level product is for. Learn more about how we test on our about page.
